Wallet Setup (One-Time)

⚠️ USE YOUR EXISTING WALLET MANAGEMENT FIRST ⚠️

If you or your agent already have wallet management (key management service, vault, HSM, custodial API, MPC signer, or any secure signing infrastructure), use that. Skip the examples below entirely.

The wallet options below are example setups for development and testing only. They have known security issues: plaintext password files on disk, private keys in shell environments, no access control, no audit trail, no key rotation. Do not use them with real funds in production. Consider this from the very start — not after you've already built around a testing setup.
